The Surva Festival is the most astonishing festival of masquerade in Bulgaria, maybe in the Balkans. This festival takes place in Pernik since the year of 1966. Since 1995 it is an international festival. It is organized as a two-days' procession of masquerade groups from Bulgaria and other countries. Traditionally 5000 people take part in the festival.
